Principle and applications of multi-point matched-die forming for sheet metal:

摘要: To reduce the cost and cycle time in fabrication of conventional stamping die, a new forming technology, so-called multi-point matched-die (MPMDF), has been developed based on discretization die. In MPMDF, fixed shape matched-dies are replaced by pair opposed matrices movable punch elements. Using generated matrices, variety three-dimensional sheet parts different shapes can be produced. Taking advantage flexibility techniques have developed, which realize formation large size with deformation. this paper, principle MPMDF described, equipment is introduced, typical application examples presented.
